In a folding communication apparatus with a housing rotatably connected by a hinge to a movable form, wherein movement of the hinge alters the speaker volume. A folding portable radio set includes a switch for reducing the speaker volume when the communication apparatus is in the open position.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A communications device, comprising: a first housing; a speaker in said first housing; a second housing; a hinge rotatably connecting said first housing and said second housing; and an electrical switch disposed within said hinge wherein rotating said first housing relative to said second housing actuates said switch thereby controlling an amplifier to adjust the volume of said speaker.
2. The communications device of claim 1 wherein said communications device is a wireless telephone.
3. The communications device of claim 1 wherein said communications device is a radio receiver.
4. The communications device of claim 1, and wherein said hinge is a double cylindrical hinge.
5. The communications device of claim 1, and wherein said switch has a first and second positions, said first position of said switch being activated when said cover is opened decreasing the volume of said speaker, and said second position of said switch being activated when said cover is closed increasing the volume of said speaker.
6. The communications device of claim 1, and wherein: said hinge is a double cylindrical hinge; and said switch has a first and second positions, said first position of said switch being activated when said cover is opened decreasing the volume of said speaker, and said second position of said switch being activated when said cover is closed increasing the volume of said speaker.
7. A method of automatically adjusting the volume of a communications device, wherein said communications device has a housing, a cover for protecting a keypad, a speaker, a hinge, said hinge having a conductor, an amplification circuit and a two position switch disposed within the hinge, comprising the steps of: opening said cover thereby rotating said hinge, said hinge's rotation causing movement of said conductor to contact said switch; powering said amplification circuit when said conductor is in contact with said switch; and depowering said amplification circuit when said conductor is not in contact with said switch.
8. The communications device of claim 1 further comprising: a manual override operable to deactivate said switch.
9. The communications device in claim 1, and wherein rotation of said first housing to a position adjacent to said second housing closes said switch, energizing said amplifier to increase the volume of said speaker.
10. The communications device in claim 1, and wherein rotation of said first housing to a position not adjacent to said second housing opens said switch, de-energizing said amplifier to decrease the volume of said speaker.
11. The communications device in claim 1, and wherein said hinge is a double cylindrical hinge, further comprising: a first cylindrical portion; a second cylindrical portion substantially concentric with said first cylindrical portion, and wherein said switch is disposed within the annular spaced defined between said first cylindrical portion and said second cylindrical portion.
12. A communications device, comprising: a housing, having a speaker therein; a cover for protecting a keypad; a hinge rotatably connecting said housing and said cover; a switch disposed within said hinge, and an amplifier coupled to said switch and said speaker, and wherein rotation of said cover with respect to said housing actuates said switch thereby controlling said amplifier to adjust the volume of said speaker.
13. The communications device in claim 12, and wherein rotation of said cover to a position adjacent to said housing closes said switch, energizing said amplifier to increase the volume of said speaker.
14. The communications device in claim 12, and wherein rotation of said cover to a position not adjacent to said housing opens said switch, de-energizing said amplifier to decrease the volume of said speaker.
15. The communications device in claim 12, and wherein said hinge is a double cylindrical hinge, further comprising: a first cylindrical portion; a second cylindrical portion substantially concentric with said first cylindrical portion, and wherein said switch is disposed within the annular spaced defined between said first cylindrical portion and said second cylindrical portion.
16. The communications device of claim 12 further comprising: a manual override operable to deactivate said switch.
